Yes I had tried all of those things, I am relatively competent and understand things having grown up in a UNIX world with my profession. I have resolved this myself - bare in mind that it only just started doing this since an MS update I believe. Years ago my PC tower was used else ware in the house. When used else ware it was via a usb wireless dongle, in my office it is, and always has been, at least for the past 3 years, been connected to the internet by ethernet cable straight to the router. I removed the long since redundant dongle licence software and the device from the list and it all started working - so why the **** did MS change something that made their software look for wireless before/over the ethernet, or fall over when it couldn't find a wireless network, instead of looking for subsequent networks. None of my other applications have struggled to find the internet, only Clipchamp and the MS store - such shoddy programming and updates with suppositions that we are all wireless.
Rant over - 'thanks for replying'
